In 2009, the tyre regulations stipulate that the two dry tyre specifications must be visibly distinguishable from each other. At the Italian Grand Prix, the soft compound Bridgestone Potenza tyres were marked with green bands on the sidewalls. The wet weather tyre was also marked with a green line in a groove.
